Noob MK channel/game question.

Ok, so I am still new to the whole wii modding thing and I've been searching for this for a while now. I am trying to learn how to burn Mario Kart and use it in mk channel. I have a mk channel.wad, and an iso of mk from megaupload (it was a 3 part iso I extracted into 1). The mk channel asks me for the game when I open the channel from my wii so I was wondering:
Can I use both the cahnnel and iso together and if so, how?

I know I have to burn the iso

(thank you for that it answered question one exactly )
but how do I use the burnt iso with the channel. What kind of Backup launcher, or loader or software should I use? Is there a tutorial out there I can go by? I'd really like to do this right, and I would also like to have wifi connect for it. As usual thank you all in advance for any help or links you can provide.
